One day, you suddenly want to go back to your old campus. Looking at the huge playground, I seemed to see myself playing with my classmates. The teaching building has become old, and I seem to see myself walking upstairs with my schoolbag on my back.

When passing by a certain class, I unconsciously glanced inside and seemed to see him. The raised corners of his mouth replaced the previous blush. Are you okay? First love
